In TMVOC, is the capillary pressure between two phases i and j:
Pc_ij = Pi - Pj or Pc_ij = Pj - Pi ? where Pi and Pj are the pressures in the phases i and j.
Thank you in advance,
Quentin
Quentin,
Capillary pressure is defined negative, i.e., it is the pressure in the wetting phase minus the pressure in the non-wetting phase, i.e., in Pc_ij, i is the non-wetting phase and j the wetting phase, and thus Pc_ij = Pj - Pi.

Thank you Stefan!
I was having trouble with the capillary pressure functions and I thought, for ICP=8, that the alpha parameters needed to be entered as negative numbers... I am relieved that I do not need to run all the simulations already done! : )
